Correlation of urinary uric acid excretion with obesity and abdominal obesity innewly diagnosed patients with type 2 diabetes mellitus / 中国糖尿病杂志

ABSTRACT

Objective To investigate the association of uric acid excretion(UUAE)with obesity and abdominal obesity in newly diagnosed patients with type 2 diabetes mellitus(T2DM).Methods A total of 1175 newly diagnosed T2DM patients hospitalized in the Department of Endocrinology and Metabolism of Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were enrolled in this study from January 2006 to December 2012.According to the quartile of UUAE,they were divided into Q1 group(UUAE＜2383 μmol/24 h,n=295),Q2 group(2383≤UUAE＜2953 μmol/24 h,n=292),Q3 group(2954≤UUAE＜3680 μmol/24 h,n=292)and Q4 group(UUAE＞3680 μmol/24 h,n=293).Clinical data and laboratory examination results were collected,and the prevalence of obesity and abdominal obesity was compared among the four groups.The associations of UUAE with obesity and abdominal obesity were analyzed.Results The prevalence of obesity was 47.9%,while the prevalence of abdominal obesity was 61.9%in the whole study population.After adjusting for age,the prevalence of abdominal obesity was higher in women than in men(P＜0.05).After adjusting for age and gender,the prevalence of obesity and MS was higher in Q4 group than in Q1,Q2,and Q3 groups(P＜0.05),and the prevalence of abdominal obesity was higher in Q4 group than in Q1 and Q2 groups(P＜0.05).Compared with Q1 group,the proportion of men,BMI,WC,DBP,FIns,2 hIns,HOMA-IR,TG,ALT,γ-GT,SUA,UAlb in Q4 group increased(P＜0.05),age,HbA1c,HDL-C decreased(P＜0.05).Logistic regression analysis showed that after adjusting for confounding factors,UUAE was a factor affecting obesity and abdominal obesity.Conclusion UUAE increases the risk of obesity,abdominal obesity and MS in newly diagnosed T2DM patients.UUAE may be used as a simple indicator to assess the risk of metabolic disorders such as obesity and MS in T2DM patients.
